Up until 2009, you could get calpol night which had paracetamol and diphenhydramine, this is a sedative/anti-histamine. And Paracetamol is addictive http://www.drugrehabwiki.com/wiki/Paracetamol as are a lot of things.
This is one of the worst references I have ever seen- full of errors and misunderstanding and with no professional standing. It is a US page. In the US the agreed name for what we call Paracetamol is acetaminophen, they do not recognise the word Paracetamol.
This is the first paragraph:
"Paracetamol is a well-known and widely used medication to treat moderate to severe pain. It is also sold under the brand name Paracod and is a brand for the generic codeine. Paracetamol works by blocking the signals in the brain that create feelings of pain and is also used to treat severe cough as it can suppress the cough reflex in the central nervous system."
Let us see how wrong this is. First sentence fine, Paracetamol is used to treat pain! Second sentence ERROR Paracetamol is not spld under the Brand name Paracod. In the US that is Acetaminophen plaus codeine (codeine is an addictive opioid). The Wiki is conflating Paracetamol with Paracod- paracetamol does not suppress the cough reflex but codeine and paracetamol PLUS codeine do suppress it.
Now the second paragraph:
"Paracetamol is often prescribed when conditions call for morphine or codeine. As a painkiller, Paracetamol is known to be nearly as potent – but not quite – as morphine. When it is used to treat cough, Paracetamol is designed to deliver even stronger relief than what is possible with codeine."
First sentence total rubbish. Paracetamol is not any equivalent for the pain relief of opioids. Second sentence doubly so!
In the UK Paracetamol and Codeine is named Co-codamol and is used for pain more severe than the lowest level.
Given that I think that any reasonable person will see that the contents of that page are totally untrustworthy.
In the rest of the page I would point out the following errors:
"Paracetamol is an opiate and therefore is a Schedule II controlled substance." WRONG.
"It has a high abuse liability and while it is very similar to morphine, codeine and other opiates" WRONG
"Paracetamol triggers the brain’s pleasure centers while blocking pain. This process contributes to its ability to generate an addiction in users." WRONG
"A tolerance for Paracetamol can be quickly developed and users may require more and more of the medication to achieve the desired effect." WRONG
"Paracetamol delivers effects that are similar to that of morphine and codeine, in addition to sedation, respiratory depression and euphoria that are less intense than morphine." WRONG
"Other side effects created by Paracetamol include, shallow breathing, slow heartbeat; feeling light-headed, fainting; confusion, fear, unusual thoughts or behavior; seizure (convulsions); problems with urination; or nausea, stomach pain, loss of appetite, itching, dark urine, clay-colored stools and jaundice." WRONG
"The abrupt cessation of Paracetamol can cause a range of unpleasant and dangerous symptoms, especially if an individual has been taking the medication for a long period of time. Cessation of Paracetamol will immediately lead to withdrawal syndrome, which closely mimics heroin withdrawal." WRONG
"Addiction to Paracetamol can be a life-threatening addiction, as well as the associated symptoms of withdrawal." WRONG
"Detoxification is required to cleanse the body of this drug and must be done under the care of a board-certified physician and a board-certified psychiatrist." ONLY IN OVERDOSE and to avoid liver failure, not for any other reason.
"Many quality treatment centers suggest comfortable detox using withdrawal medications specific to Paracetamol abuse. A quality center will do a full physical on a person to determine the right medications for comfortable detox. This method helps to correct the chemical imbalances and should be combined with psychological evaluations and other medical care." UNNECESSARY as Paracetamol is not addictive.
There is hardly a correct statement there as they are conflating two different preparations.
No weight can be given to evidence from that page at all. It is the worst reference I have ever seen!
